We have a lot in common- I've been wearing Ray-Bans for years, but at age 75, I am fortunate in that my distance vision is still 20/15 uncorrected with no galucoma or floaters. I also shot at both "Death Valley"/ Quantico-- and at Fort Benning and Camp Perry- rifle competition inter-Service league. But in 'Nam- the gold plated style frames of the Ray-Bans were a non-no for snipers and their scout/spotter team-mates-- the old mantra of "No Rattle- No Shine" put the kiabosh on the "diddley-bop shades" in a hurry.
Shooting glasses- not a SC or Skeet man per se, but when I do shoot clays at DU Sponsor events, I were Decots-100%, just as I wear shatterproof safety glasses when using chain saws or any power tools used in carpentry/construction projects. And as a long-time welder, who is very lucky to enjoy the gift of Chuck Yeager type vision into his retirement years, the precaution of using shooting glasses when shooting any firearm, or in the hunting field mileu, is SOP-100%..
